摘　　要：实用的组播计费机制是IP组播能够在域间得以广泛部署的前提条件.从不同参与者的角度讨论了IP组播的3种典型的服务模型及其相应的可实施的计费策略.这3种模型代表了域间组播的多种可能情况,它们是ICP-USER模型、ICP-ISP模型以及ICP-ISP-USER模型.分析了每种模型所对应的应用场景、解决方案以及提出算法的复杂性等.整个Internet被看作是一个生态系统,该工作利用博弈论的思想,尊重各个参与者的目的和利益,使得Internet的自组织特性得以充分体现,有利于Internet中"生态链"的长期、稳定和健康发展,具有很好的实用性.A practical pricing mechanism is the foundation for the deploying of IP multicast in the inter-domain Internet. The IP multicast service model and its pricing mechanism are discussed in this paper, by considering the motivations of different partners in the process. Three models are proposed for all applications in the real environments. They are ICP-USER model, ICP-ISP model and ICP-ISP-USER model. In every model, the applied scenarios, resolving method and the complexity of algorithm are described. Here, the Internet is considered as an ecosystem. So the work embodies the self-organization property of the Internet based on the game theory, and respects every role＇s fight and benefit, which is good at the health and stable development of the Internet. So it has great practical feature.
